5.13's in a 44 and you're just waiting for the gears to implode. He's got the 3.6 engine. Really he shouldn't need more than 4.56 with 4.88 being the more aggressive.

 

...and I'm not saying it can't be done as I personally know someone who is running 5.13's and wheels it but he's just waiting for the day they do implode lol

...he's running the old 3.8 engine with 37's

 

mel wade from ORE ran 5.38s in his wifes jeep Evolander for 70k+ miles and stock d44's so 5.13's should be fine....I ran them in my other jeep with 35's and will in my new jeep with 37's. just need to put away the cash to do it...

 

5.38's sure if you're overlanding it. No biggie...

Next come the pics where it crawled a couple of times....if it can do Fordyce and the Rubicon at least twice *no winching* on 5.38's then I'll run for cover.

 

I disagree, I feel 5.13's are ok in a D44. I've been running them for 4 years with 37's and lots of wheeling never had a problem. I wheel fairly tough trails like windrock, hard rock, etc but don't wheel redlined spinning tires and bouncing.

 

I guess it all depends on who you ask. Doing further research on a couple of older threads, it looks like 4.88 / 5.13 would be borderline. So I stand corrected.

Factors that come into play seem to be in the realm of what engine you have, auto or manual, reside at high elevation or not, do you actually drive over 80mph, what kind of wheeling is actually done (overlanding vs. crawling), and if you actually "get on it" aka spin tires / bouncing.

This is actually good (knowing 5.13's are relatively safe) since now I'm not as worried running possibly 4.88's in the D44 rear. It seems in some cases at the higher gears, more people were actually imploding axle shafts & u-joints more versus the r/p.

I also disagree, I run 5.38 in a D44 with 37" Pitbulls. That's about 125lbs per tire/wheel combo. Folks have been running 5.13 and 5.38 in the D44 for years without issue.

 

As I just mentioned above, 4.88/5.13's is the "safe" line (assuming 3.6 and auto trans)....


** Also keep in mind that unlike the OP, I have a d30 up front which is why my thinking automatically goes into 4.56/4.88 as the "safe" zone even though we're talking d44's lol **

These new Gen Dana Super44s (FourWheel Mag said it should have been renamed the Dana48 ) as they are known by Dana, have a larger 8.8 Thick cut ring gear and heavier pinion then the 8.5 ring gear in the older version D44. The 5.38 is plenty strong but is too much gear for the 3.6 in which the transmissions are geared differently. It is however, perfect for a 3.8L auto on 37s... (2100rpm at 60mph)
